IMPROVEMENT IN WAS-BOILBRS- 'dit' tlgemle ttfettrt trim time trtttts uttnt mit mating tutt nf the Seite.

TO ALL WHOM IT MAY CONCERN:

Be it known'that I, CHARLES E. MILLER, of Indianapolis, Marion county, Indiana,`have invented a certain new and useful Wash-Boiler; and I do hereby declare the following to be a. full, clear, and exact description thereof, reference being had to the accompanyirig drawings, making part of this specification.

This is an improvement in the class 4of wash-boilersin which the suds, being subjected to a forced circula.- tion, and expelled through suitable spouts uponv the clothes, a very effective detergent-action is. secured.

The improvement over my patent, granted June 23, 1868, consists in employing, instead of the perforated bottom, raised pit-covers, having imperforate tops and perforated sides, by which means I prevent the stoppage o f the pcrforations by the mass of clothes, and also reduce the liability of a reflux of water upward through the boiler-bottom. p

Figure 1 is a. longitudinal section through a wash-boiler, provided with my improvements.

Figure 2 is a perspective view of one of my spouts detached. V Y v A represents a common oval wash-boiler, of thc kind having two drops or pits, B B', to enter the boileropenings of the stove. i

To each pit there is fitted a device whichI call the spout C or Cwhich spout, although fitting tightly within the pit when in usc, is susceptible of being'readily lifted out of the pit when so desired. 4

Each spout is composed of the following parts: D is a. cover to the pit, consisting of a disk, d, and rimd', the former, in conjunction with the rim, screwiugto close the opening of the pit, andthe rim itself having, justvunderneath the disk, a series of'apertures, df; which afford a communication from the body ofthe boiler into the spout at this part. A. raised head, d", on thcrim el', limits the entrance of said rim into the pit.

E is a perforated diaphragm,which is so fixed within the spout as to extend obliqucly across the pit,in the manner represented.

The olice of the perforated diaphragm E, besides that of passing the cold returning waterthrough its apertures e, is to direct the heated and ascending suds into the pipe or column G, which extends upwards, with a gradually-contracted areaV within the boiler, to nearly the top thereof. The top of the pipe G is closed, as shown, und said pipe is providedgneur its top, with two necks, gg', to which are fitted the nozzles or spouts proper, H H', lof which'cach is capublcof beingdirectcd more or less upward or downward, so as to cause the jet of suds lto strike such portion oflthc clothes 4as maybe desired, These adjustable nozzles may be substantially such as are described in my patent of 23d of June, 1868. I

The operation of my boiler is as follows: Each pit having been momentarily uncovered by lifting the spout, a small piece of soap is placed in each pit, and the s pout'return'cd to its place. The clothes (preferably presonked) are then packed into the boiler, as shown, and water poured in, in quantity suilicient to cover them. As the water becomes heated, it rises within euch pit, und, strikingr the oblique diaphragm E, is by it deflected toward that side of the pit which is nearest the pipe G, up whose narrowing interior it rises, with constantly-accelerated velocity, to escape upon thc surface of the clothes in the form of jets of considerable force. A

The water, as fast as heated, escaping from the pits, its place is supplied by the colder water, which, having percolated through 'the substance of the'clothes, enters the pits through the apertures d and c, to hc again heated and expelled in the manner already described. I

' It will be seen that the detuchability of th'e spouts and nozzles enables any portion to be inspected and' cleansed, and also enables the boiler to be used in the customary form, whenever so desired. V

The situation of the apertures d on the sides of tho sputs, and under the overhanging disk cl, is highly advantageous in several respects. Y d Being removed from direct contact with the clothes, the latter are not liable to'bc streaked with rust, or

torn by contact with the Vedges of the apertures, nor are Vthey liable to be drawn into said apertures by the motion of the descending current, so as to partially or wholly close the apertures, and thus stop the circulation of suds. v v

I have selectedforl illustration the'form of spout which practica)` test has proved to he eectua, but do not desire tov restrict myself to the precise form here represented; for example, an inferior modification of my invention may have discharge-nozzles projecting rigidly from the pipe, instead of being adjustable, es here shown.

I 'claim herein as new, and of my'invention y i The varrangement of cover D, having' perforated rim d and nperforated top d, obliqne and perforated diaphragm E, pipe G, and nozzles g g', substantially as eet forth.

In teetimony of which invention, I hereunto set my hand. A
